You actually brought up a good point. Anyone who lists out things on what type of people shouldn't message them are immediate red flags! I understand she doesn't want to waste her time, but she's on a fucking dating website! She can simply ignore the unwanted messages without making herself look like a total ass from the get-go.

Yup! Being too negative, or only wanting people without flaws (or in this case, perceived flaws) will make sure you stay single forever. Don't get me wrong, a person has to have standards when dating, and some self respect, but holding out for perfection is just ridiculous.
